KlingMotionControl - ComfyUI Built-in Node Documentation

The Kling Motion Control node generates a video by applying the motion, expressions, and camera movements from a reference video to a character defined by a reference image and a text prompt. It allows you to control whether the character’s final orientation comes from the reference video or the reference image.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	A text description of the desired video. Maximum length is 2500 characters.	STRING	Yes	N/A
`reference_image`	An image of the character to animate. Minimum dimensions are 340x340 pixels. The aspect ratio must be between 1:2.5 and 2.5:1.	IMAGE	Yes	N/A
`reference_video`	A motion reference video used to drive the character’s movement and expression. Minimum dimensions are 340x340 pixels, maximum dimensions are 3850x3850 pixels. Duration limits depend on the `character_orientation` setting.	VIDEO	Yes	N/A
`keep_original_sound`	Determines if the original audio from the reference video is kept in the output. Default is `True`.	BOOLEAN	No	N/A
`character_orientation`	Controls where the character’s facing/orientation comes from. `"video"`: movements, expressions, camera moves, and orientation follow the motion reference video (other details via prompt). `"image"`: movements and expressions still follow the motion reference video, but the character orientation matches the reference image (camera/other details via prompt).	COMBO	No	`"video"` `"image"`
`mode`	The generation mode to use.	COMBO	No	`"pro"` `"std"`
`model`	The Kling model version to use. Default is `"kling-v2-6"`.	COMBO	No	`"kling-v3"` `"kling-v2-6"`

Constraints:

The reference_video duration must be between 3 and 30 seconds when character_orientation is set to "video".
The reference_video duration must be between 3 and 10 seconds when character_orientation is set to "image".
